1. Usage of flowmeter
The usage of flowmeter is to install the flowmeter, connect the power and signal lines, then calibrate the flowmeter. Once everything is ready, you can start measuring. The installation position of the flowmeter should be on the straight section of the fluid pipeline, avoiding installation near equipment such as bends, pumps, valves, etc. Before installation, check whether the model, specifications, accuracy and other parameters of the flowmeter meet the requirements. During installation, attention should be paid to the inlet and outlet directions of the flowmeter to avoid reverse installation. Flow meters generally require connection to a power supply and signal lines. The power supply is usually 220VAC or 24VDC, and the signal line is usually 4-20mA or RS485. Before connecting, check whether the polarity of the power and signal lines is correct to avoid short circuits or reverse connections. The flowmeter needs to be calibrated after installation, and before calibration, the zero and full points of the flowmeter should be checked for correctness. Calibration should be carried out according to the user manual of the flowmeter. Generally, it is necessary to compare the standard flow rate value with the actual flow rate value and make adjustments based on the comparison results. After the calibration of the flowmeter is completed, the measurement can begin. During the measurement, attention should be paid to whether the temperature, pressure, density and other parameters of the fluid meet the requirements. During measurement, the stability of the flowmeter should be maintained to avoid external interference and vibration. Precautions for proper use of flow meters

2、 Regular maintenance and upkeep of flow meters require regular maintenance and upkeep, such as cleaning, calibration, and replacement of parts. Regular maintenance and upkeep can extend the service life of flow meters and ensure measurement accuracy.
3、 Overloading and overcurrent should be avoided during the use of flow meters to prevent damage or affect measurement accuracy. During use, attention should be paid to the rated flow range and maximum flow range of the flowmeter to avoid using it beyond the range.
4、 Avoid vibration and impact during the use of flow meters to prevent damage or affect measurement accuracy. During installation and use, attention should be paid to the stability and shock resistance measures of the flowmeter.
2. Wiring method of flowmeter
The wiring method of flowmeter may vary depending on different types and brands.
. Here are two common wiring methods for flow meters for your reference.1. Wiring method for split type flow meters: As shown in the above figure, the sensor and accumulator of the split type flow meter are installed separately and connected through signal cables. When wiring, it is necessary to connect the output signal of the sensor to the input terminal of the integrator. Generally speaking, the wiring method of a split type flowmeter is relatively sim
